Pump-type laundry washing machine

ABSTRACT

This invention is a vertical machine for washing and wringing clothes by mean of a closed pumping circuit which supplies the washing or centrifuging system. The washing system uses a special eductor which produces a cavitation effect above the clothes, combined with a rotary washing system which produces the paused circulation of the clothes; the rotation of the washing system is produced by the same water flow. The centrifuging is made in the inner tub impelling its rotation by means of a turbine, thus the tub rotates over the virtual axis which passes through the center of gravity thereof and the clothes for being wringed, furthermore is used a special annular chamber for auto-balancing. The rotation of the tub over the virtual axis is achieved making float the inner tub by means of the special supports which combine the speed components of any point of the tub. The basic ideas of the above concepts are applied in different practical versions, as well as with modifications to a horizontal axial axis or front-loading washing machine or an industrial washing machine.

BACKGROUND OF THE INVENTION

The current vertical washing machines of clothes use agitators, eitherof the oscillating type or propeller type, to scrub the clothes andproduce streams inside the washing tub which pass through the fabric andtry to loose the particles adhered thereof; but these streams are notstronger and effective to go through the innermost fibers of thethreads, therefore the time of washing can be more prolonged and tospend more energy of the necessary. These washing machines requiremechanisms of machined transmission and speed reduction to produce theoscillating motion of the agitation impeller or in the case of propellerthrusters; these tend to entangle so much the clothes. In addition,during the wringing of the clothes by centrifugation, the tub rotatessupported by a fixed central axis; this makes difficult the balanceduring the rotation.

This invention is an improvement to the U.S. Pat. No. 5,953,939registered by the authors of this in the United States of America. Thepurpose of this invention is to improve the machines for washing,rinsing and wringing clothes; in addition to take advantage in some waythe phenomenon of cavitation for a more efficient washing. The inventionis referred to a machine for washing clothes by means of a recirculationpumping system, which uses a special eductor to produce cavitationinside the washing tub and, for the wringing it has a self-balancedrotation system which makes that the tub turns on the virtual axis whichpasses through the centre of gravity. With these improvements thepurpose is to obtain a deeper and uniform washing, to circulate theclothes by the cavitation area inside the tub; besides to decrease thelosses of pressure in the hydraulic circuit. Also, as variants, it isshowed how to apply all these new ideas to a horizontal or front loadwashing machine and an industrial washing machine.

In this document are presented the basic ideas of the invention andtheir variants, with the purpose to combine in the most practical waythe most ideal to get a washing and wringing machine which increases theefficiency and speed of washing, and saving time and energy during itsoperation.

DESCRIPTION

In the following description and in the attached drawings thecharacteristics of the invention are detailed, indicating the portionsof this one with the same reference signs as in the description as infigures; the portions with equal function on the different figures aremarked with the same number in each of them.

FIG. 1 represents a first version of the washing machine, in which isdescribed, in general, the recirculation pumping system which is usedfor squirting inside the washing tub and propelling a turbine which, bymeans of a speed reducer, it moves a rotary washing system whichproduces the circulation of the clothes inside the washing tub.Furthermore, it is showed the centrifuging which makes rotating thefloating tub on the virtual axis passing through its center of gravity.By simplicity, the eductor system is not showed.

FIG. 2 shows a special eductor and a rotary washing system which isimpelled by a jet reaction; this jet is sent towards a dragging zone topush the clothes inside the tub.

On FIG. 3 is observed a first version of the use of the rotary washingsystem of FIG. 2, as well as a first form to arrange, staying fixed onthe system, the special eductor and the steam chamber which feeds it toproduce steam bubbles which produce cavitation in the bosom of thewashing tub.

FIG. 4 is a variant of the rotary washing system of FIG. 3, used toreduce friction losses in the pipeline. In this version, The eductorrotates along with the rotary washing system, while the steam chamberremains fixed, therefore it is inserted a rotary sealing system,mechanical-type seal, on the tube which carries the steam between thestatic steam chamber and the suction of the eductor rotating.

FIG. 5 is other similar system to the previous, in which the steamchamber and the eductor rotate together to avoid the use of a rotatingseal, besides employing a planetary reducer to transmit the rotation tothe system.

FIG. 6 describes a mechanism so that the rotating of the washing systembeing paused.

In FIG. 7, the feeding to the rotary washing system is made below of thetubs. In this case, the rotary washing system moves laterally togetherwith the centrifuging tub, during this cycle; therefore FIG. 8, ascontinuation of FIG. 7, shows mechanisms to allow the displacement inthe case of using a speed reducer.

On FIG. 9 the same system of FIG. 7 is showed, except that in thisfigure the rotary washing system remains centered with the geometricaxis of the washing machine and the steam chamber is fixed.

FIGS. 10 and 11 describe a system for better balance of the centrifugingtub.

The FIG. 12 is a mechanism, in addition to the flotation system, tosupport the tub during the centrifuging cycle in its free rotation, onany virtual axis passing through the center of gravity of the tub andthe clothes for wringing.

FIG. 13 is a variant of FIG. 7 or 9, which uses the support of FIG. 12;and a pump is used for the washing pumping circuit and another pump forcentrifuging cycle; both pumps impelled by the same motor.

On FIG. 14 is showed a system to eliminate loose threads coming out ofclothes.

On FIG. 15 is illustrated how to implement the new washing andcentrifuging system described in the previous figures, in a new washingmachine of drum or cylinder type or horizontal axis or frontal load typecylinders.

FIG. 16 is equal to FIG. 15, except that the washing system changes alittle.

On FIG. 17 is used the basic idea of FIG. 12 to the case of FIG. 15 or16; and FIGS. 18 and 19 are variants of the same idea applied to awashing machine of vertical axial axis as of FIG. 7, 9 or 13.

On FIG. 20 or 21 is used the system of FIG. 18 or 19 for a version ofthe washing machine of FIG. 3 with less losses.

The FIG. 22 is an industrial washing machine for washing largequantities of clothes, and FIG. 23 is the wringing system of the washedclothes in the system of FIG. 22.

FIG. 24 is a second version of the industrial machine of FIG. 21 inwhich the wringing is made by centrifuging the clothes.

FIG. 25 is a version of FIG. 9 and FIG. 26 is an optional system of aplanetary speed reducer which produces an oscillating motion which puttogether the blades to produce the circulation of the clothes inside thetub.

The FIG. 27 is an industrial version similar to FIG. 25. The FIG. 28 issimilar to FIG. 9.

Support structures, controls, cabinet, etc., for simplicity are notshowed in the figures.

Returning to FIG. 1, it is seen that the new washing machine has a maintub (7) within which is placed an internal tub (14) which has about halfof the height of that the nodding of the internal tub being when itrotates floating, within the main tub, with the clothes to squeezeseated at its bottom, within the main one. A closed annular chamber (28)forms the side of the internal tub (14) and contains, as a counterweightto balance on the centrifuging cycle, a certain amount of a heavy andfluid material, such as a kind of liquid or small spheres of smoothmaterial. The internal tub is housed in a broadening of the lower halfof the main tub (7), so that the diameters of both tubs are sufficientlymatched. The peripheral separation between the broadening stage of themain tub and the upper edge of the internal tub is covered to avoid thepassage of clothes, by a kind of annular floodgate (31) with section on“L”-shape, whose vertical portion adjusted slightly adjusted to theinner of the main tub; and the horizontal portion is supported by ownweight, on the upper edge of the internal tub. The horizontal portion ofthe “L” has pasted below a plate (30) of antifriction material, whichseats and slides on another plate (30) of the same material fixed at theupper edge of the internal tub, when it rotates.

In the center of the bottom of the internal tub (14) it is lifted up awide vertical tube (11) which terminates, at its upper, in the box of aplanetary speed reducer (2) and, through the tub, it is extendeddownward into another tube (20) to drain the water from the tub. Underthe lower end level of the tub, a vertical and axial turbine (26) iswithin a broadening, on casing shape of the vertical tube (11) so thatthe turbine shaft (32) impels to the planetary reducer and entering tothis through a bearings box (33) with seal against leakage of thelubricant. On the other hand, centered shaft (34) of the reducer output(2) is welded, by above of this one, to the center of the upper lid (35)of a second wide tube or central hollow post (1) hereinafter calledcentral post. This central hollow post is outer, concentric and freelyadjusted to the wide tube width (11), also it is hermetically closedonly in its upper portion with such lid (35); around this central postare fixed one or two helical plates (4) which to rotate the post theyserve as screw, to be pushing the clothes downward. Also are fixed tothe central post (1), at the bottom of the tub, radial blades (12),which when rotate through towards the periphery the clothes which arefalling to the bottom of the tub. The central hollow post, the helicalplate welded to it and the system which makes rotate to both to move theclothes inside the tub, form the rotary washing system, in this figureand following.

The washing and rinsing cycles are made by means of a closed circuit ofpumping. The circuit consists of a pump (18) placed under the tubs andwith its discharge connected, through the tube (8) and the control valve(13), to a nozzle (6) or a special eductor (not shown in the figure bysimplification) which discharged in suitable direction a strong waterjet inside the tubs. By the orifices (10), that both tubes, (11) and(1), have at the upper of their periphery, the water flow continuouslygets out of the internal tub through central tube (11) and the tube ofevacuation (20) to impel the rotation of the turbine (26). By means ofthe speed reducer (2), the rotating motion of the shaft (32) of theturbine is transmitted, with smaller speed and greater force, to thehollow central post (1) to move the clothes with the blades and thehelical plates. The upper of both tubes lacks of orifices and is closedin order to when fill with water the tub a compressed air chamber (3) beformed within them which prevents that the water reaches to the systemof the reducer. In order to facilitate more the movement of the clothes,the tubs have in their inner periphery other helical plates (5) which,with the circular motion of the water flow within the tub, cause thatthe clothes tend to ascend by the sides of the tubs.

The water which gets out of the turbine discharge continues flowingthrough the tube of evacuation (20) of the internal tub and, getting outof this one, it enters directly to the suction tube (19) of the pump(18) that returns the water flow to those to complete the closed circuitof pumping.

The wringing cycle is carried out through the centrifuging of theclothes. For this, it is started by evacuating the water of the tubs bymeans of some draining system, not indicated on FIG. 1, until the waterlevel decreases as far as below of the bottom of the tubs, so that thewater which is in the internal tub (14) gets out through the retainer orcheck valves (27) at the bottom of the tub. To finish evacuating thewater at such level, becomes to introduce water so that the spacebetween the two tubs be filled until certain predetermined level (29);due to the retainer valves (27) of the internal tub, the water will benot introduced again in this tub, which will be floating in the waterthat there is between both tubs. The evacuation tube (20) of theinternal tub also has a retainer valve (15) with floating plugger, whichserves to when introducing again water between the two tubs and duringcentrifuging the same water it does not enter again for this tube to theinternal tub.

Floating the internal tub, this is rotated by means of a special turbinespecial and similar to a horizontal turbine Pelton-type. This turbineconsists of a vertical box (25), of almost cylindrical shape, which iscentrally joined at the bottom of the tub or to the vertical evacuationtube (20) and is crossed by this one; at the side of the box areintroduced at the half a distributed series of simple cavity-radialbuckets (24) slightly tilted downwards with similar form to a ladlecurved almost 180°, which allow free way to the inner of the box onlythrough their cavities. Moreover, as it is observed in the cutting AA′,the internal edges of the buckets (24) are directed and finish in aseries of holes (21) which the evacuation tube (20) has in its side ofthat zone, thus the water of the jets that impel to the buckets isdischarged by such holes within the tube. These water jets are thrown bya series of nozzles (17) on the cavities of the tangential-shapebuckets; therefore the impulse applied on the buckets by the jetsproduces the rotation of the internal tub (14)

To make work the turbine described on the above paragraph, the controlvalve (16) of the nozzles (17) connected to discharge of the pump (18).The water flow which impels the turbine is drained by the evacuationtube (20) on the input of the suction tube (19) of the pump (18), sothat this same flow being pumped again towards the nozzles (17), and beestablished the closed circuit of pumping, which keeps the rotation ofthe turbine. The water which wets the clothes and is centrifuged isevacuated of the internal tub by the holes (9) of the tub which areabove of the flotation level. All the system which produces the rotaryimpulse of the tub is lodged in a cylindrical casing (23) or centrifugedchamber which is centrally joined to the bottom of the main tub (7), asa continuation of this one, and whose bottom is connected to the suctiontube (19) of the pump.

Since the internal tub (14) does not rotate supported by a rigid shaftwhich supports this in its geometric center, this shall rotate, due toits flotation, on the virtual axis which passes through the center ofgravity of the set of the tub and the clothes for being wringing.Although the internal tub (14) rotates in balanced form or withoutvibrations on this virtual axis, if the clothes are not symmetricallydistributed inside the tub, the virtual axis displaces from thegeometric axis, causing that the tub shakes and oscillates by notrotating on its geometric axis; therefore it may hit or rub with themain tub (7). This undesirable effect is diminished by means of thefluid and heavy material contained in the closed annular chamber (28)which forms the side of the tub (14), since when beginning to rotate thetub the liquid within this chamber is accumulated from the side opposedto the slipping of the virtual axis respect to the geometrical. When theweight of the accumulated fluid in a side of the chamber counteracts tothe unbalanced weight of the clothes in the opposite side, the distancebetween the virtual rotary axis and the geometric center will decrease,although it will not be null and it will be in an intermediate point,since when approaching to these axes it is redistributed, until certainpoint, the fluid inside the balance chamber (28), but improves theoscillation and the shaking. Between the sides of the tubs are placedbearings with shock absorbers, not shown in the figure, to supportfrictions and small impacts between the tubs. Later on, some methods areindicated to avoid the redistribution of counterweight fluid.

So that the flotation of the internal tub inside the main tub be stable,is added a flouting counterweight (22) in the lower end of theevacuation tube (20); in this form the meta-center keeps fixed betweenthe flouting centre and the center of gravity of all the system of theinternal tub, including wet clothes.

FIG. 2 illustrates a rotary washing system, similar to that described inthe above figure, which uses the impulse of a jet reaction to rotate thecentral post with its helical plate, in such a way that the rotation ofthe post is combined with a positive push of the same water squirt uponthe clothes, in order to cause its movement into the tubs and itscirculation through the area where cavitation occurs. In the samedrawing is described the aforementioned special eductor.

In the upper portion of FIG. 2 the device is observed de device toproduce the positive push on the clothes, which consist of a draggingzone of the clothes limited by two warped surfaces, (44) and (45),separated to some distance facing each other, with opposing curvaturesand certain convergence degree between both; in such a way that theclothes, which are in the limited space by both surfaces, can undergo apush or effective drag by a water jet that flows between both surfacesin direction of the convergence and which gets out of a nozzle, a tubeor from the eductor illustrated in the same figure, as a jet producer inthis case.

Also in the upper portion of the figure it is seen that the specialeductor is comprised, firstly of a conical tube or Venturi (39) fed by atube (40), which increases the speed and lows the water pressure to anegative pressure. The outlet end (41) of the Venturi, of smallerdiameter, is enclosed and surrounded by a small closed cylindrical boxor suction chamber of the eductor (37) communicated, through a smallsuction tube (38), with the upper portion of a closed chamber (57) (FIG.3), described later, where low pressure steam is generated. The suctionchamber (37) ends in an output tube (36) with an equal diameter to thefinal outlet diameter (41) of the Venturi and aligned with the output ofthis one; in order to absorb the steam there is a very small clear (42)between the final extreme (41) of the Venturi (39) and the initialextreme of the output tube (36). The output tube (36) of the eductor hasin its beginning a short and small internal contraction that form thethroat (43) of the eductor and then it keeps its normal diameter at fulllength, to keep the vacuum pressure produced by the Venturi and thethroat, contrary to a normal eductor which ends in a diffuser. The waterfed by the tube (40) to the Venturi (39) of the eductor and the steamsucked by this from the steam chamber are launched by the output of theeductor (36) in a jet of water mixed with steam bubbles a vacuumpressure, which collapse due the atmospheric pressure to be dischargedinto the tub, causing implosions and shock waves which wash the clothes.

In the bottom of FIG. 2 is showed the system that produces the impulseto rotate the center post (1) with its helical plate (4), by the jetreaction in a rotary tube (48) fed by the fixed tube (8) connected tothe pump discharge. To the left of the bottom of the figure it isobserved a first type of rotary coupling between these two tubes, whichallows the rotation of the first one over the second one, consisting inintroducing some distance to the end of the feeding tube (8) within therotary tube (48), with a fine adjustment between both, as a sleevebearing. The axial displacement between both tubes is limited mountingon the fixed tube (8) a shoe of sliding (52), in disc shape with smoothsurfaces, which is linked or slightly imprisoned between a pair of discsor rotary plates, also with smooth surfaces, which are joined or linkedto each other in their periphery. The upper plate (51), with a bushingslightly fitted to the fixed tube, it supports the rotation of thesystem on the upper surface of the shoe of sliding (52) and the lowerplate (50) is joined to the rotary tube (48), in order to support it.

Another version of the rotary coupling between the fixed tube (8) andthe rotary tube (48) is illustrated in the drawing to the right of theprevious version. In this case, the fixed feeding tube (8) ends in acylinder (54), wide and hollow, which at its inner has screwed theexternal diameter of a large bushing (53), which serves as a sleevebearing to the rotation of the rotary tube (48), for which the upper endof this tube is introduced within the bushing with a fine adjustment.This bushing (53) is smoothly fastened, in its inferior face, by a shoeof sliding (52) mounted on the rotary tube and, in its upper face, byanother screwed bushing (55), as a nut, in the end of the same tube.

In the left inferior portion of FIG. 2 it is observed that the verticaland centered rotary tube (48) within hollow post (1), has in its lowerend a first (46) fold to 90° and it continuous, after to get out by ahole at the post, with a second (47) horizontal fold, also near to 90°which places to the end (40) of exit of the tube on perpendicularposition to the rotary axis of the own tube, and some distance from thisaxis and directing the water jet which launch by such end towards thedragging area, formed between the surface (44), terminal of the helicalplate (4), and the surface (45) of another inferior plate welded to thesame central post (1), in order that the water jet drags the clotheswhich pushed by the rotation of the helical plate, they gradually stayon this space.

The distance and perpendicular direction with respect to the axis of therotary tube (48), with which the water jet gets out by the end (40) ofthe same tube, according to their folds to 90°, it causes that this jet,by reaction, pushes the end of the tube backwards and impels therotation of this. The transmission of the rotation of the rotary tube tothe central post can be directly done, joining with arms (49) the postto the rotary plate (50) of the tube, or by means of a speed reducer toincrease the torque and to reduce the speed of the central post, so thatthe helical plate (4) is moving the clothes towards the dragging zone.

The FIG. 3 is a washing machine by recirculation pumping with washingand centrifuging systems similar to those described in FIG. 1, exceptthat the rotary washing system is impelled with a tube which rotates byjet reaction, as the described in FIG. 2; in addition, it is showed theuse of the special eductor in the rotary washing system and thedisposition of the steam chamber (57) which produces this to negativepressure. In this case the steam chamber and the eductor remain fixed,joined to the feeding tube (8), to be able to directly connect theelectrical power to the resistance (56) that heats the water in thesteam chamber and feeding directly the produced steam to the suctionchamber of the eductor. At the bottom of FIG. 3, it can be seen anamplification (67) of the eductor and the steam generating system, whichare indicated with the same number (67) at the upper of the tub (7).

The feeding tube (8) for the washing centrally gets into the inner ofthe tubs, (7) and (14), by above of these, and it is directly connectedwith the conical tube or Venturi (39) of the special eductor, in such away that this together with its suction chamber (37), crosses and keepcentrally lodged inside the steam chamber (57). The steam chamber is acylindrical box, hermetically closed and lodged within the central post(1), wherein the water is heated by means of the electrical resistance(56) to generate steam to the low pressure of the eductor; this steam issuctioned by the suction chamber (37) of the eductor through the smalltube (38) whose nozzle stays at the upper of the steam chamber to drawin only this. Below bottom of the steam chamber (57) protrudes,centrally, the output tube (36) of the eductor to coupling, by means ofthe support shoe of sliding (52) and the rotary plates (50) and (51) asin FIG. 2 with the rotary tube (48) which keeps the same small diameterof the output tube (36), to keep the high speed and the low pressure ofthe water and steam flow produced by the eductor, as it was mentioned.Joined by and arms (49), the rotary tube (48) drags in its rotation tothe central post (1); furthermore the lower portion and the folds (46)of the same tube are housed within a broadening of the bottom of thecentral post o cover (58) in bell-shaped, in order to avoid that theclothes stuck with such folds. The end (40) of the rotary tube (48)outstands of the cover (58) by a hole in a radial and vertical plane(66) that interrupts the bell shape, so that the water jet and steambubbles, which are discharged by such extreme, go towards the draggingarea formed between the surface (44) of the helical plate (4) and theplate (45), wherein the bubbles are collapsed causing shock waves whichwash the clothes.

Within the internal tub (14) another additional tub is placed (59),separated a little and with a series of holes (10) by which is leavingthe water that the tube (40) discharges within the internal tub. Throughthe space (60) between the bottoms of the two tubs, the water goes outof these through a evacuation tube (20) which begins from the bottomcenter of the internal tub (14), and it extends downwards until endingvery near, upon the input of the suction tube (19) of the pump (18), tocomplete the closed pumping circuit during the washing cycle.

In order to fix the flotation level (29) in FIG. 3, firstly the water ofthe tubs is evacuated (62) by means of a small pump (62) whichdischarges (63) to the general drainage and whose suction (64) isconnected to an output (65) of the main tub (7), which is at the side ofthis to the same height that the prefixed flotation level (29). When thewater level comes at the height of the opening (65) cannot be continuedevacuating the water and the level (29) of the same one does not getdown anymore; in this point, main pump (18) starts and begins to suck,through its suction tube (19), the water of the centrifuging casingbottom (23) simultaneously that it discharges this same water in jetslaunched by the nozzles (17) upon the Pelton turbine, which begins torotate and return the water used to the bottom of the casing (23)through the tube (61), coaxial and external to the tube (20), to bere-circulated again by the pump. Since the water passage of theevacuation tube (20) to the suction tube (19) is more direct, this onewill suck more water of the inner of the tube (20) that water evacuatedby the turbine. Thus, the tube (20) will be emptied at certain volume,same which will go out from the internal tub (14), but it could notretake it due to retainer valve (15) inside the own tube; in this way,the volume of water evacuated of the internal tub increases, in equalamount, the volume of water which there was between the two tubs,therefore the water level between them will increase, exceeding theopening (65). In this condition, the draining pump (62) come back towork removing the excess and repeating the cycle until the internal tubbe empty and floats the rest of the cycle.

In the FIG. 4 only it is drawn, by simplicity, a rotary washing systemwhich is a variant of the system of FIG. 3, which is used if thepressure losses in this are big. In FIG. 3 the rotary tube (48) has asmall diameter, equal to the output of the eductor (36), which canproduce big friction losses due to the high speed of the water in thetube and its curvature. To limit these losses, keeping a big diameter inall the rotary tube (48), in FIG. 4 the eductor is installed on the end(40) of the tube (48), after his double curvature (46) (47), connectingsuch extreme (40) directly to the Venturi (39) of the eductor.

The cylindrical closed steam chamber (57), which is fixed to be able tofeed directly to the electrical resistance (56), is housed within thecentral post (1) and it is centrally crossed and supported by a passingwide tube (69) which is continuation of the feeding tube (8). The lowerend of the wide tube (69) protrudes of the bottom of the steam chamber(57), the enough to be articulated with the rotary tube (48) by means ofa rotary coupling with the shoe of sliding (52) linked by the rotaryplates, lower (50) and upper (51), as it was described.

The connection between the fixed steam chamber and the suction of theeductor, which rotates with the system, consists of a thin vertical tube(68) which, with its upper end inside the chamber, sucks the generatedsteam and then it gets into the side of the passing tube (69), in such away that its lower end stays concentric or coaxial with this tube, andconnected to the borehole of a small vertical bushing (70) of thickwall, fixed by means of an arms (73) to the inner of the wall of thepassing tube (69). Below the bushing (70) it is introduced in theborehole of this second thin and short tube (76) which can rotate insidethe bushing, slightly adjusting its diameters as a sleeve bearing. Thissecond short tube (76) is connected, through a small flexible hosesection (72), with a equal third tube (38) which goes down centrallyuntil being placed within the rotary tube (48), wherein it is fastenedby a ring (74) fixed to the inner of the rotary tube by another arms(73); then, the third tube (38) goes out from the rotary tube (48)through the wall thereof and it is directly connected with the suction(37) of the eductor. The sealing of the connection between the fixedportion and the rotary portion of the duct of the steam is made with amechanical or rotary seal comprising a disc (71) or ring that has itsupper surface polished and is tightly mounted around the second thintube (76), which is pressured against the lower face, also polished, ofthe bushing (70), pushed by a spring (75) which at the lower end issupported against the ring (74) which holds the third tube of steamconduction (38). The flexible hose section (72) serves so that thespring can push the sealing disc. In such a way, the steam sucked by thefixed tube (68) can flow by the tube (38), which turns with the eductor,towards the suction chamber (37) of this. The disposition of the othercomponents of the rotary washing system is equal than in FIG. 3.

As an option, the steam chamber (57) of FIGS. 3 and 4 can be fixed toany other place outside the central post, using a connection tube (38)or (69) with the suction of the eductor of enough length.

The FIG. 5 is similar to the washing system described on FIG. 4 and itshows, in addition, the tubs (7) and (14). The difference consists inthat the steam chamber (57) is not static and rotates joined to therotary tube (48). Furthermore it is showed the planetary speed reducer(2) which transmits the rotation of the rotary tube (48) to the centralpost (1). The feeding tube (8) also enters by the upper of the tubs andit articulates to the rotary tube (48), of equal diameter, through thealready described rotary coupling which comprises a support shoe ofsliding (52) and the rotary lower (50) and upper (51) rotating plate.The planetary reducer (2) is centered within the post and above of therotary coupling between the tubes. The driving gear (79) of the reduceris mounted in a bushing (78), joined at the upper plate (51) andslightly adjusted slightly to the feeding tube (8). The shafts of theother gears of the reducer, which are fixed to transmit the torqueforces, are mounted on a round support (80), fixed to the feeding tube(8) which also serves to support the rotation of the post (1) through abearing system (81).

Below the rotary connection, the cylindrical steam chamber (57) isintegrated to the rotary tube (48), thus, the tube centrally crosses thechamber. The rotation of the eductor and the steam chamber (57) togetherwith the rotary tube (48), allows the continuity between the internaltube (68) of the steam chamber and the tube (38) which feeds from thisto the suction chamber (37) of the eductor be made with out thenecessity of use a rotary seal. The power supply to the resistance (56)that heats the water of the steam chamber is done indirectly, eitherthrough a sliding socket connection over the copper or brass rotaryrings, as it is described below, or by means of an electric transformer,whose primary is fixed and the secondary, turning with the othercomponents, it feeds to the electrical resistance. Other form to heatthe water stored in the chamber is by heat conduction through the wallsthereof, placing a heater close to the outside of these walls. Theseheating systems are not shown in the figure.

As in the FIG. 4, the curved portion, (46) and (47), of the rotary tube(48) and the eductor are confined within the cover (58) which in thiscase is separated of the central post (1). It is observed that, withinthe cover, the curved portion of the rotary tube (48) and its end (40),connected to the Venturi (39), increase their diameter, as far aspossible, to decrease the pressure losses. The output tube (36)outstands of the plane (66) of the cover (58) directed towards thedragging zone which is formed by the end (44) of the helical plate (4)and the bottom surface of the tub (59). By the front of the exit of theeductor (36) and the dragging zone, the cover (58) has welded ahorizontal plate (77) curved upwards (see the cutting of the AA′section), which serves to the water jet and the dragged clothes beingdeviated upwards of the tub and the rotary impulse of the water mass ofwater around the post be broken, so that in the other spaces of the tubthe streams being slow and the clothes not be so much ruffled.

The FIG. 6 is a mechanism which controls the paused rotation of a rotarywashing system, which uses a planetary speed reducer to transmit therotation of the rotary tube (48) to the central post (1). The figureonly shows a zone of the central post (1), with the rotary tube (48),the planetary speed reducer (2) at the upper and the controllingmechanism at the bottom, with a portion of the bell-shape cover (58).

It can be seen that the mechanism firstly consists of a thick ring ofrectangular section (87) or cam ring, concentric with the rotary tube(48) and fastened by a radial arms (49) to the inner wall of the centralpost (1). The upper surface of this annular plate (87) or cam ring isdivided in any appropriate number of sections which comprise, each ofthem, a low surface portion or valley (89) followed by a slope whichfinishes in a top or flat crest (88), as cam path. In each section, fourin this figure, a corresponding leg (86) with a rounded and slipped endthat in whole supported and slipped over each of the paths, by above ofa second heavy ring (85). This ring is mounted on the rotary tube (48)and lashed or locked to this by means of a longitudinal wedge (90) fixedto the own tube, in such a way that, with light adjustments, the ring(85) can slide along the tube but not rotate respect to this. Therotation of the second ring (85) and, therefore, from the rotary tube(48) is stopped when the upper face of this ring is pressed against astopping plate (84) adhered to a no rotary third ring (83). The thirdring (83) can be a little raised to separate the stopping surfaces andto release the rotation of a second ring (85) and, consequently, therotation of the rotary tube (48), of the eductor (2) and the post (1).Thus, the third ring has at the upper an articulated handle to the endof a lever (91), which raises the ring to rotate in its other end over apivot encrusted on a bar (92) which, passing through the free space ofthe reducer (2), it is fixed to the support (80) of the gear shafts;thus this disposition avoid, on the other hand, the rotation of the ring(83). To stop of release the rotation of the tube, allowing that thethird ring presses over the second or separating to these, the levermoves vertically by a valve rod (93) articulated in the middle portionof the lever and acting by springs and any mechanic system orelectromagnetic of control.

By means of the reducer and this mechanism, the paused rotary cycle ofthe rotary tube (48), coordinated with the rotation of the post (1) andits helical plate, is carried out by the driving frequency of the valverod (93) and by the relative rotation between the rotary tube (48) andthe cam ring (87) which rotates, together with the post, slower than thetube. During this relative rotation, the second ring (85) locate itslegs (86) upon the high cam paths and it is pressed against the plate(84) of the third ring (83), stopping its rotation and the one of set.The stopping lasts until that the valve rod (93) raises to the thirdring a time to releases again the rotation, which, when continuing, doesthat the legs of the second ring fall in the low cam path, avoiding thestopping until that the mentioned rotation puts back them into stoppingposition and the cyclic position of the output tube of the eductorrespect to the dragging zone, must be such that allow the pausedcirculation of all the clothes through the tub, with out entangle somuch.

The FIG. 7 is, basically, similar to the rotary washing system of FIG.5, except that the system is below the tubs (7) and (14), connecting thefeeding tube (8) to a passing hole (103) which is at the center bottomof the centrifuging casing (23). Over the passing hole (103) is fixedvertically, as a continuation of the feeding tube (8), a short stretchof flexible hose (102) whose upper end joins a first short and rigidtube (101), staying these two loosely housed inside the draining tube(61) of the centrifuging turbine. This first rigid tube (101) isintroduced certain distance within a second tube (100), joined to thecenter of the bottom of the internal tub (14) and which crossing this,it rises within the tub until a height a little above of the establishedfloating level (29) prefixed of the same tub. This arrangement servesto, without interrupting the continuity of the feeding duct, the secondtube (100) and the tub can rotate on the first tube (101) and, at thesame time, they move with this one laterally in any direction due to theflexibility of the hose, allowing the rotation of the floating tubaround any virtual axis during the centrifuging.

A third tube or rotary tube (48), equivalent to the tube (48) of FIG. 5,is inserted into the second tube (100) by the upper portion of this,until that a ring-shape smooth shoe of sliding (99), which has each ofthe tubes, settled one on the other to support the weight and rotationof the third tube over the second one.

The aforementioned tubes are introduced one into the other with a fineadjustment, as a sleeve bearing, to allow the free rotation between themand to form, together with the initial hose, the duct to feed the rotarywashing system as continuation, with equal big diameter, of the feedingtube (8).

In the FIG. 7 it is seen the upper end of the rotary tube (48) thatfinishes off and debouch into a closed chamber (97), in form of dome orof a double wall-widen bell, so that the tube (48), gradually openingits diameter, is connected with the inner peak of the bell, whichcentrally surrounding the tube, it enlarges and unfolds until the tubbottom. Over the upper end of the rotary tube (48) there is a conicalappendix (98) which, with the vertex directed downwards, serves as adeflector for the flow which goes out by the mouth or upper end of thetube (48) deviates 180 degrees towards the periphery and the bottom ofthe double-wall bell, where the same bottom and the two walls of thechamber (97) are extended and converge (see cutting of AA′ section) insuch a way that they are molded in a circular exit (107), horizontal andtangential, which is connected with the conical and gradual entry, of ahorizontal, curved tube (40) of big diameter matched to the bottom ofthe bell. As well as in FIG. 5, the tube (40) is connected to theVenturi (39) of the eductor, in such a way that this stays within thecover(58) which is a radial extension of the bell-shape chamber and onlythe outlet tube (36) of the eductor protrudes through a hole in avertical and radial plane (66) in which ends the cover, directing thedischarge of the water jet and steam bubbles towards the dragging zoneformed by the surface (44) of the helical plate (4) and the bottom ofthe tub (14). In front of the dragging zone is fixed to the chamber (97)a curved plate upwards (77), with the same function described in FIG. 5.The rotary coupling of the tube (48) with the second tube (100) and thewater jet discharge, perpendicular to certain distance of the center, bythe output tube (36) of the eductor produce a pair of forces by jetreaction which makes rotating the washing system, as it was described.Due to the big section of the bell-shaped chamber (97), the losses bychanging the direction of the flow within them are minimal.

In order to feed to the suction (37) of the eductor by the steam chamber(57), rotating both with the rotary washing system, this is placedinside the central post (1) in such a way that the same connection tube(38) of the steam is used to join the bottom center of the steam chamberwith the dome center of the bell-shape chamber (97) to make rotate that.The upper end (68) of the connection tube (38) stays within the steamchamber in order to suction this and its lower end (104), welded to thedome, and continues its connection until the suction (37) of theeductor.

At the upper of the steam chamber (57) is welded a shaft (105) whichmoves the central gear (79) of a planetary speed reducer (2), whichtransmits the rotation of the chamber to the central post (1). In orderto transmit the pair of the impelling shaft (105) it is necessary thatthe shafts of the others intermediate gears (96) be fixedly supportedrespect to the system; but, on the other hand, all the rotary washingsystem must be able to move in any lateral direction according theinternal tub moves while centrifuging. Over the reducer (2), is placed around plate (80) which supports such shafts, and it is joined by above,to other upper plate (95) fixed to the structure (94) of the washingmachine by a flexible tube (106) which supports the twist, in order toallow, with out rotating, the lateral displacement of the support platetogether with the rotating system. In addition, the plate (80) registersthe rotating of the upper end of the impelling shaft (105) in a centralbushing and, at its periphery, the rotation of the central post (1). Thepower supply which in this figure appears within the flexible tube(106), to the resistance (56) of the steam chamber is detailed in FIG.8.

The FIG. 8 is an amplification of the upper portion of the central post(1) of FIG. 7 and shows two variants more of the system which allows thelateral displacement of the support of the shafts of the speed reducer(2). As in the previous figure, these variants have a round plate (80)which supports the shafts of the gears (96) of the reducer and also itregisters the rotation of the impelling shaft (105) and of the centralpost (1).

Before continuing, it is taken advantage of FIG. 8 to describe the powersupply to the resistance (56) of the steam chamber (57) (FIG. 7). Thesupport plate (80) extends upward in a box (108) within which aremounted two rings of copper or brass (109), electrically isolated at theend of the driving shaft (105) joined to the steam chamber. Each ring(109) is connected to a terminal of the electrical resistance (56) bywires, sealed within an axial hole (not illustrated) in the same drivingshaft (105) until the resistance (see FIG. 7). The electrical energy isfed by brushes (110) which slide on the rings (109) during the rotation.

Over the box (108) of the support (80) of the shafts, it is centrallyfixed a horizontal bushing (111) inside the one that freely slides around bar (114), in whose ends are welded, perpendicularly to them andcentered, other round bars (112). Each of these two bars freely moves intheir turn within set bushings (113), one on each side of the bar, whichare joined to a plate (95), fixed to the structure or lid (94) of thewashing machine. In summary, the mechanism consists of fixing the box(108) of the support (80) to a first track to slide, which allows tomove it along a shaft, and this first track to slide is fixed to anothersimilar track to slide which moves in perpendicular sense to the firstone, therefore the device, combining both perpendicular displacements,allows to the support moves in any lateral sense, but not rotate.

At the right bottom of FIG. 8 shows one third variant of the system thatholds the supported plate (80) so that this can move laterally,combining a linear movement with another angular. Over the support box(108), a horizontal round bar (114) is introduced within a bushing (111)that can slide freely through the bar and articulated rotate to avertical bolt (118) fixed at center of the box; furthermore, an end ofthe bar can rotate on another bushing (116) articulated to anothervertical bolt (115) fixed to the structure (94) of the washing machine.To avoid the tendency to rotate of the plate (80) and its box (108), areplaced a bumper (117) on the box (108), so that when beginning to rotatethe plate this bumper blocks the rotation with the bar side (114).

The FIG. 9 is a washing machine equal than FIG. 7, except that the steamchamber (57) is fixed and can be placed outside the rotary washingsystem which remains centered with the geometric axis of the washingmachine, without moving with the internal tub (14) during thecentrifuging cycle.

As in the FIG. 7, the feeding tube (8) is connected with the centralpassing hole (103) drilled in the background of the casing ofcentrifuged (23) and on this hole it is fixed directly, onto a shoe ofsliding or base ring (120) of smooth surface, a first short tube (101)as continuation of the feeding tube (8). In this case, the short tube(101) is introduced, with sleeve bearing fine adjustment within thethird rotary tube (48) described in FIG. 7, in such a way that this onecan freely rotate over the short tube, supporting its shoe of sliding orlower smooth ring (99) over the base ring (120), to support the rotationand the vertical thrust of the washing system. As passageway so that therotary tube (48) is introduced into the internal tub (14) and finishesoff within this in the bell-shape chamber (97), a second tube (100)rises from the center of the bottom of the inner tub (14) up to oneheight greater than the flotation level (29), to avoid the entrance ofthe water to the tub during the same flotation. The second tube (100),opposite to the same tube of FIG. 7, does not fit to the other tubes andit must be of such diameter that it keeps enough clearance between itand the rotary tube (48) and equal clearance with the inner wall (119)of the bell-shape chamber (97), so that the tub (14) and the same secondtube (100) can laterally move during the centrifuging, with out collidewith the chamber or with the rotary tube.

The conduction of the steam from the fixed steam chamber (57) to thesuction chamber (37) of the eductor is made firstly by means of a thintube (68), which connects the upper zone of the steam chamber with theinner of a closed box (108) within the central post (1). This box servesfor the passing of the steam to a second vertical thin tube (38), whoseupper end is introduced, with smooth adjustment, into the closed boxacross a central bushing below the same box, since having its lower end(104) welded to the centre of the dome of the bell-shaped chamber (97)the tube (38) must rotate over the bushing and at the entrance of thetube (38) a rotary seal is placed to avoid leaks. The connection of thesteam is completed through another thin tube or hose connected betweenthe lower end (104) of the second thin tube and the suction chamber (37)of the eductor. In the second tube (38) is mounted the input gear (79)of the planetary reducer (2) and the support (80) of the shafts thereof,integrated to the passing box (108), it is fixed to the lid (94) or themachine structure. In such a way the thin tube (38), in addition tocarry the steam to the suction of the eductor, it serves as impellingshaft of the speed reducer and as shaft which support the upper of therotary washing system, which rotates centered and does not require ofthe mechanisms described in FIG. 8.

The FIG. 9 also shows another system to fit the flotation level (29) ofthe tub before the centrifuging. The system consists of a closedcontainer (126) which has a volume equal than the water volume which isbetween the two tubs and the flotation level (29), excluding the freevolume within the centrifuging casing (23). Below the closed container(126) there is a small draining pump (62) which connects its input orsuction (122) to the bottom of the main tub (7) through a valve (121)and its output or discharge (124) to the lower end of the closedcontainer (126) through another valve (125). Additionally to this firstconnection, it is added another pair of tubes with their control valves(123) which connect the suction and the discharge of the pump, byexchanging the initial connection between these with the tub and theclosed container, respectively. At the top, the container (126) has atube (64), with its control valve (127), which connects it to the output(65) of the main tub (7) on the flotation level (29); moreover alsohaving a waste-pipe (63) to drain it to a high level.

After the washing or rinsing cycles and keeping closed the valves (123)the draining pump (62) is started with the valves of the firstconnection, (121) and (125) opened in order to evacuate the water of thetubs until the level of the lower end of the main tub (7), transferringit to the closed container (126); in such a way that the excess of waterwhich passes over the volume of the container is evacuated by thewaste-pipe (63) to the general drainage and only remains, therefore, inthe container (126) the necessary volume to fill again the space betweenthe tubs at the flotation level. When the level of the extracted waterbecomes below of the bottom of the internal tub (14), the retainervalves (27) of the bottom of this open and allow the exit of theremaining water thereof. After emptying the tubs, the valves (121) and(125) of the initial connection are closed and are opened the two valves(123) of the second connection, so that the water flow is invertedbetween the container and the tub, in such a way that all the waterstored in the container (126) is returned to the main tub, so that thewater level between the tubs reaches the prefixed flotation level. Whenthe water, which is returning to the main tub (7), reaches to the bottomlevel of the internal tub (14) the retainer valves of this one are closeand avoid that the entrance of water to the inner thereof, thus, thistub stays floating to start the centrifuging. With the opened valve(127), the excess of water from the squeezed clothes, which comes out ofthe internal tub, is drained by output tube (64) at the side of the maintub towards the closed container (126), keeping the flotation level(29).

FIG. 10 is amplification, for better clarity, just of the lower part ofthe tub (7) and of the tub (14) with their central tube (100) and thebalancing chamber (28), of FIG. 7. This chamber, as variant of thechamber of FIG. 1, not only includes the first annular portion (28) ofthe flank of the internal tub, but also it continues in a second portionor cylindrical cavity (129) below of the basis of this tub, in such away of double bottom crossing by the central tube (100). The annularportion (28) of the chamber is divided by vertical plates (128) in aseries of cells, opened and communicated by below with the secondportion of the chamber (129). These vertical cells are of two types,both alternately distributed from the side of the tub.

Each cell (133) of the first type is divided in two portions by means ofa horizontal plate (130). The upper portion is separated of the rest ofthe chamber by the plate, forming a compartment (131) which has a seriesof holes (10) in its inner wall and another series of holes (132) byabove of the flotation level (29), in order to not affect this one, inits outer wall; thus, the first type of cells serves to evacuate fromthe internal tub (14) the recirculation of water flow. The lower portionof these first cells (133) has the same function as the second type ofcells. Within the compartments (131) can be placed filters.

The cells of the second type (134) lack of holes and they are directlycommunicated to the double bottom of the tub (129), which stores, whenthe tub is not rotating, the fluid and heavy material which serve ascounterweight to balance. If the clothes are not distributed when thetub is rotating the virtual rotary axis, which passes through the centerof gravity, it will move at certain distance of the geometrical axis ofthe tub towards the overweight is, in such a way that the cellsdiametrically opposed to the overweight keep with a greater rotationradio that the cells closed to the overweight, provoking the tendency bythe centrifuging force, that the counterweight flow enters in greateramount into the opposed cells than the closed to the overweight. To isincrease the balance of the tub by this distribution of the fluid andhowever that, for the same reason, the virtual axis moves to coincidewith the geometrical axis, the flow trapped in each of the second cells(134) could not be redistributed in the whole annular chamber as in FIG.1, since the separating plates (128) of the plates impede it to do it,which allows to continue keeping the initial balance.

The FIG. 11 shows only the lower zone of the main tub (7) and of innertub (14) of FIG. 10, making greater vertical scale than the horizontal,in order to describe more clearly a mechanism which is added to thebalancing chamber of FIG. 10 to improve the performance of this same.The mechanism is housed at the second horizontal cylindrical portion(129), centrally crossed by the tube (100) of the chamber (28) and itworks obstructing the passing of the balancing fluid towards the cell ofthe second type (134) from the overweight side by compensating andallows this passing towards the cells of the opposite side. Inside thecylindrical cavity (129) of the balancing chamber, there is a horizontalbar (135) with a ring (138) at its center slightly adjusted to thediameter of the support tube (100) which serves as shaft so that the barrotates respect to the geometrical center of the tub. At a side of thebar (135) is mounted a small counterweight (136) which can slide overthe bar and whose sliding towards the end of this one is limited by aspring (137), which works to compression with little force. Near theentrance of the cells, the other end of the bar is joined to the centerof a light and vertical plate (139), which has a width, a curvature anda length such that obstructs the passing of the fluid towards somecells.

If the weight of the clothes is asymmetrically distributed when the tubstarts to rotate, the geometrical axis of the tub or the passing tube(100) and, therefore, the bar (135)) together with its central ring(138) will rotate around the virtual rotary axis which is displaced tocertain distance from the geometrical axis; by the above, thecentrifugal force applied to the counterweight (136) will cause that thebar rotated on its ring (138) until that the counterweight (136) staysdiametrically opposed to the virtual axis or to the clothescounterweight, compressing the spring (137) to go towards the end of thebar. In this position the obstruction plate (139) covers the entrance ofthe balancing fluid to the cells of the second type (134) of the sidewhere the overweight is, until the fluid which goes into the oppositecells compensates the weight undistributed. As the weight is balancedwithin the tub, the virtual rotary axis approaches to the geometricalaxis and the centrifugal force on the counterweight (136) is annulled tocoincide both axes; at the same time, the counterweight (136) stops tocompress the spring (137) and it is passed, pushed by this, towards thecenter to its initial position; this movements provokes, by theconservation of the angular moment, that the counterweight (136) the bar(135) and the obstruction plate (139) tend to increase their rotaryspeed rotating faster than the tub, so that the position, with respectto the cells, of the bar (135) and the plate (139) is indifferent andthe rest of the balancing fluid is uniformly distributed in them.

The FIG. 12 is a mechanism which supports to the internal tub during thecentrifuging, coincide or not its virtual rotary axis of rotation withits geometric axis. It is considered the speed of any point of the tubis equal to the speed of the point respect to the geometrical axis ofthe tub plus the speed of this axis respect to the virtual axis.

In this figure only is showed the zone of the lower portion of the tubs,main (7) and inner (14), and the new mechanism which supports to theinternal tub. The first portion of the mechanism consisting of aplatform (146), centered under the internal tub (14), which has acentral hole which is loosely cross over, by a guiding tube (145), whichis joined to the tub center, below its bottom. The rotation and theweight of the internal tub are supported by a circular tier or series,concentric with the tub, of vertical wheels (143) with shafts fixed tothe platform and directed in a radial form to the center of the tub.Other series of horizontal wheels (144), with their vertical shafts alsofixed to the platform, are distributed around the periphery of theplatform hole, in such a way that the wheels, supporting their rotationon the surface of the guiding tubes (145), keep and guide the concentricrotation of the internal tub (14) respect to its geometrical axis and tothe platform (146). The speed of any point of the tub due to thisrotation, concentric to the geometric axis of the tub, constitutes thefirst component of the absolute speed of the same point.

The second portion of the mechanism allows that the platform movesfreely in any lateral direction; for this a series of supports is placedunder the platform to sustain it. Each support consists of a horizontalbushing (147) with a round bar (141) of certain length within it, overwhich the bushing slides freely as sliding track; the bushing cantransversely rotate to its geometric axis on a vertical pivot (148)fixed to the platform below this one, at the same time that the bar(141) can move horizontally and angularly, rotating over one of its endswelded to another bushing articulated to a vertical pivot (142) anchoredthis on the bottom of the main tub (7). So that each of the bars (141)did not support in cantilever the weight of the tub which transmits toit its sliding bushing (147), at the other end of each bar, opposed tothe rotation, it is mounted a vertical wheel (140) with its collinearshaft to the bar and from such diameter which rolls tracing a circlesupported over the bottom of the main tub (7), when the bar movesangularly. The combination of the linear movement of the sliding bushing(147) on the bar (141) and the angular displacement of these over one oftheir ends, it gives freedom to the platform (146) to displace in itshorizontal plane in any lateral direction, without rotating.

Another form to support the lateral displacement of the platform (146)consists holding this to a first sliding system which moves in certainhorizontal direction, being this first system fastened in its turn to asecond sliding system fixed to the main tub, which moves alsohorizontally, in a perpendicular direction to the first system.

The second portion of the mechanism described in the last twoparagraphs, in any of its two versions, allows that the platform (146)supporting to the internal tub, and carried or driven by this same,moves horizontally, tracing a circle equal than the circle that tracethe geometrical axis of the tub around any virtual axis on which rotatesthe tub. This movement of the platform provides to any point of the tubthe second component of the total speed, with which such point movesrespect to the virtual axis over which the tub rotate.

The FIG. 13 is the same washing machine than in FIG. 7, except that themechanism of FIG. 12 is added to support the rotation of the internaltub (14). In addition, are used two centrifugal pumps coupled to thesame submersible motor (150), which are within the centrifuging chamber(23) supported by a plate (152) which hangs from the platform (146) ofthe same supporting mechanism from FIG. 12.

One of the pumps (149) directly feeds the jets of the nozzles (17) whichimpel the special turbine Pelton, whose box (25) is joined to theguiding tube (145) from the lower end of the tub. The feeding tube (8)connected without a valve to the discharge of another pump (18) isinserted directly, with smooth adjustment into the passing tube (100) ofthe tub over which rotates the tube (48) of the same rotary washingsystem from FIG. 7. The suctions (19) of both pumps stay directlysubmerged within the centrifuging chamber (23), where continuouslyre-circulate the water to establish the two closed pumping circuits. Thetwo centrifugal pumps operate with different rotary direction, with thepurpose to operate either the rotary washing or centrifuging system; itis enough to change the rotary direction of the engine or motor in itsfeeding wires (151), sealed and flexible, activating the performance ofa system and deactivating from another one, without the need of usecontrol valves. The engine or motor with two pumps of opposite rotationcan be used in the other cases described here.

The FIG. 14 is a device for disintegrating the threads that the clothesloosed and to avoid that they obstruct the performance of the pump (18).The device is mounted within a large diameter tube (159), interposed inthe suction tube (19) through a conical tube (155). The device consistsof a rotating knife (157) of several blades, mounted transversely in anextension (156) of the driving shaft of the pump, cutting the threadswhich the water carries against other fixed blade (153), also of severalsheets by adjusting the pressure between them with the spring (158) atthe end of the shaft. Rotating blades (157) also pressed against a plate(154) below with multiple perforations that retain some threads to becrushed by the blades against the same plate.

The FIG. 15 shows a washing machine of two horizontal tubs andfront-loading, similar to the common of this type, in which are appliedthe new concepts described in the previous figures. As in those figures,the washing machine has a main tub (7) which in this case, is a drumplaced horizontally, with a circular, chamfer or conical opening (161)on its front face and within which is placed, centrally, another rotaryhorizontal drum or internal drum (14). This last drum has multipleperforations (10) and a series of parallel blades (5) internal weldedalong its side, furthermore a circular opening (168) chamfered on itsfront face, to introduce the clothing. To contain the water inside thedrums, the front opening (161) of the main drum (7) is closedhermetically by a conical periphery cover lid (162) with a sealedgasket.

During the washing or centrifuging, the internal drum (14) should beadapted to rotate within the main drum (7); for this, the main drum (7)has, in the back side and housed towards its inner, a first wide andshort tube (174) joined by its rear end to the rear center of the drum,with free passing to the inner of this one; in such a way that thisfirst wide tube remains, with a smooth adjustment, into a second widetube (175) with its front end welded externally in the center of therear part of the inner drum (14); thus the rotation of the internal drum(14) is supported on the rotation of the second wide tube (175), as asleeve bearing, over the first wide tube (174), as a support shaft.

On the other hand, the rotation of the inner drum (14) at its front endis supported on a wheel (167), with conical periphery, which fits in theround opening (168) chamfered from the drum and rotates with this. Theshaft (163) of the hub (165) of this wheel (167) rotates supported by abearing box (164) sealed and joined to the center of the lid (162) ofthe main drum (7), so that this lid (162), pulls with oneself to thesupporting wheel (167) to close or to open, for putting or to removingthe clothes. To have an adjustment pressure of the linkage between thewheel (167) and the internal drum (14), the wheel hub (165) internallyhas a compression spring (166) which supported at the inner end of theshaft (163) pushes to the cube so that the wheel be pressed over theopening of the drum.

Also in FIG. 15 the washing machine works with a pumping closed-circuitwhich feeds of power to the washing or centrifuging, connecting the pumpdischarge (18) to each of these two systems and their suction (19) tothe lower side of the main drum (7). Due to during the centrifuging, asit will be seen in the figure below, the drums move together with theirconnection pipes to the pump (18), in these pipes are interposed somehoses (102) with enough flexibility to absorb such movements.

The washing is made, as in prior cases, by a special fixed eductor fedby a tube (8), with control valve (13), connected to the discharge ofthe pump (18) and with the suction of the eductor connected to a chamber(57) steam generator, also fixed. The back and central connector, fromthe water flow for the washing is made using a conical intermediateamplification (172), with a deflector nucleus (173) also conical in itscenter, to connect the feeding tube (8) with the back end of the firstwide tube (174) of the main drum, in such a way that this tubeintroduces the flow inside the inner drum, passing through the wide tube(175) of this. The wide feeding tube (174) is connected and endscentrally, within the inner drum, on the basis of a cylindricalhorizontal box (97) which serves to direct the flow towards the input ofthe eductor; in such a way that the big area of the section from thesetwo components decreases the speed of the flow, and thus, the frictionlosses by the changes in its direction. So that the water flow acquiresa rotary impulse to enter in the cylindrical box (97), it is placedwithin the first wide tube (174), along to this and until the back sideof the cylindrical box, a duct or helical plate (160) which gives thismovement to the flow. The flow which is entering to the cylindrical boxwith such movement is directed, through a volute (176) within the box,towards an output tangential tube (40) in the box periphery. The outputtube (40) ends in the Venturi (39) of the eductor, which directs itsexit downwards and the most tangentially possible over the blades (5)from the lower side of the inner drum, in such a way that the water jetand the bubbles, colliding against the blades, impulse the rotation ofthe inner drum to shoveling with the same blades to the clothes, in thebosom from which cavitate the bubbles. The connection between the steamchamber (57) and the suction chamber (37) of the eductor is made by athin tube (38) which enters, by the wall of the first wide tube (174),towards the cylindrical box and the eductor within this.

In order to make the wringing by centrifuging, in the second wide tube(175) is mounted a common Pelton turbine (170), which is impelled bywater jets which collides over the buckets (24) and they are launched bynozzles (17), with control valve (16), connected to the discharge of thepump (18) therefore, thus, the turbine drag in its rotation to the innerdrum holding back the wet clothes for wringing. In the front face of thebuckets is perforated a small hole (169) in which finish a radial thinduct (171) which is until the inner surface of the second wide tube(175), with the purpose that the rotation of this tube be lubricatedwith a small portion of the same water which launch the nozzles over thebuckets.

The FIG. 16 is a variant very similar to the horizontal washing machineof the FIG. 15 and, as in this figure; the connector of the feeding isthe central back part of the main drum (7). In this case the feedingtube (8) is directly connected with the Venturi (39), in such a way thatthis, the output tube of reduced diameter (36) and the suction chamber(37), fed by the fixed steam chamber (57) through the tube (38), whichcompose the special eductor, are housed securely fixed within the widetube (174). This tube is joined to the center of the main drum (7) andserves as shaft of the inner drum (14), which rotates with to the secondwide tube (175), like a sleeve bearing, on the first wide tube (174).The output tube (36) of the eductor, which is as short as possible,protrudes slightly from the back of the inner drum (14) and it curvesslightly downward in order to launch the jet of water and steam bubblesupon the underside of the drum. The end of the output tube (36) iscovered with a disc (58) close to the back side of the inner drum and ofrounded surface to avoid that the clothes be hooked with such end.

In this case, the closed pumping circuits for the washing and for thewringing are separated, so that the hydraulic circuit which feeds theeductor is fed by a centrifuge pump (18) which operates with a sense ofrotation opposite to the centrifugal pump (149) of the circuit ofsqueezed, both pumps being driven by the same motor with rotatinginterchangeable to activate one or another pump. This double pumpingcircuit has the purpose of to operate alternately each circuit, in sucha way that to operate the wringing pump (149), this launch a water jet,through of its tube and the discharge nozzle (17), over the buckets (24)of the Pelton turbine (170) joined to the inner drum to rotate this alittle bit and to make the shoveled of the clothes by means of the innerblades (5) of the drum. Then the rotation of the motor is changed tooperate the pump (18) and activates the washing action of the eductor,repeating adequately of the two cycles slowly.

The FIG. 17 shows the system which allows to the inner drum (14) of theFIG. 15 or 16 rotate, during the centrifuged, over the virtual axiswhich passes by its center of gravity. This system is similar to thedescribed on FIG. 12 and is based also in a support, equivalent to thesupport (146) of this Figure, which support to the tub or inner drum(14) rotating over its own geometrical axis, while the support and thedrum move laterally around the virtual rotation axis. In this case, thesame main drum (7) has the function of the mentioned support since theinner drum rotates centrally inside the main drum. The system whichholds the main drum and allows it to move laterally, in any direction,consists of 4 lugs (177) welded symmetrically to the sides of the mandrum (7) in four points, two in front and two at the back. En each lugis articulated, by a horizontal pivot (148), a vertical bushing (147)which can rotate transversally to its geometrical axis over such pivot.Within the bushing it moves, in a sliding track form, a vertical roundedbar (141) whose upper end articulates a pivot (142) which allows to thebar oscillate in angular form, as pendulum, over such end in aperpendicular plane to the axis of the drums. In the lower end of eachbar (141) is fixed a spring (178) which supports the weight of the drumssupporting the bushings (147) over the upper ends of the springs.

To avoid that the forces of the vertical movement of all the previoussupports system of the drums be transmitted to the structure (94) of thewashing machine in vibration form, this system in its turn is fastenedto another system which consist on fixing respectively the two pivots(142) of the fore oscillating bars (141), and equally in the two pivotsof the rear end, to each one of the ends of an horizontal bar (179) inwhose middle part is raised a vertical rod (183) are articulated, inrotary form, an end of each of the other two bars (184) which areopposite, each one towards a side of the rod, and sloping downwards withcertain angle, as normal position. The other end of each of these twosloping bars, also is articulated in same rotary form, to acorresponding second horizontal rounded pushing bar (182) which runswithin a bushing (180) fixed to the structure (94) of the washingmachine. The movement in opposite sense of these last two horizontalpushing bars (182) is limited by springs (181). Thus, the force of themotion vertical upwards and downwards of the horizontal bar (179) isprojected by the two sloping bars (184) in two horizontal forces, equaland opposite to each other, over the bars (182) and the pushing springs(181) to both sides of the rod; moreover of the little verticalprojection of this force just produces pairs o torsion efforts contraryin each fixed bushing (180), in such a way that the forces over the twosprings and the torsion pairs over the two bushings are opposite tothose from the other side, therefore, the reactions over the structureof the washing machine are equal and opposite, therefore, the verticalmotion force is transformed in inner efforts over the structure,annulling as vibration producers.

To decrease the movement of the virtual axis of rotation respect to thegeometrical axis of the drum, as in FIG. 1, annular balancing chambers(28) are placed, surrounding each end of the inner drum (14).

The FIG. 18 is a variable of the FIG. 12 to avoid the vibration in thecentrifuging, similar to the system on FIG. 17, but applied to avertical washing machine, in such a way that the main tub can be movelaterally to be supported by a special supports system, while theinternal tub rotates over its geometrical axis within the main. Thewashing system is the same of FIG. 7, except that the feeding tube (8)of the eductor enters directly into the main tub (7) fixed to this andadjusted to the inner of the central passing tube (100) of the internaltub (14), in such a way that, furthermore, the tub can rotate over itssame passing tube (100) coupled to the Pelton-type turbine (25) andregistering its rotation in a bushing (185) that the main tub (7) has inits center. Although it is not required, is convenient that the tubfloats so that the weight thereof over the bushing is less.

The mechanism which during the centrifuging allows to the main tub tomove in any lateral direction comprises in a series of supports whichsupport to the tub below and around this, similar to the wheels whichaligns automatically in the direction of the displacement towards anyside. In this case each support comprises a flat horizontal bar (147)which in one of its ends is articulated a bearing of vertical shaft orpivot (148) fixed to the bottom of the tub, which allows that the baroscillates in a horizontal plane over such end. The flat bar, followingthe movement of the tub, moves lineally in any of both senses supportedover the upper periphery of a vertical wheel (186) whose mounting (141)can rotate horizontally over other bearing of vertical shaft (142), sothat the wheel can align in any moment with the direction of the bar.Below of the box which support to this last bearing (142) is welded aguide vertical bar (188) which slides within a support bushing (187)fixed to the structure (94) of the washing machine. Between the bearingbox (142) and this supporting bushing (187) is placed a spring (178)which works to compression, as a shock absorber to support the weight ofthe set in its displacement around of the virtual rotating axis. Thevertical wheel (186) always must keep a minimal distance from the pivotor bearing (148) of the bar, with the purpose of that exist a pair whichinduces the aligning of the bar with the direction of the displacementof the tub in each moment.

On the other hand, the connection pipes, (8) (17) and (19), between thetubs and the pumps (18) (149), have, as in FIG. 17, intercalated astretches of flexible hoses (102) to allow the lateral movement of theconnector tubes together with the main tub (7) respect to the pumps.

The FIG. 19 is a variant of the supports in FIG. 18, therefore, alsothis new supporting system (189) of the main tub (7) serves so that thiscan displace laterally in any direction, while the internal tub (14)rotates over the shaft (194), which registers its rotation in thecentral bushing (185) of the main tub and it is impelled by the aforedescribed turbine system (25).

The new system consists in a supporting series (189) which support tothe main tub (7) distributed around its upper periphery. Basically eachsupport consists in a horizontal crosshead of two bars or shaft (191)joined in its center to 90°, in such a way that one of the shaftsrotates in its ends over the laterals of an upper inverted U-shape plate(190) welded to the upper portion (187) of the structure of the washingmachine through the fixed bar (193). The other crossed shaft rotatesalso over the laterals of the other lower U-shape plate (192) from whichhangs the upper end of a second bar (141) which passes loosely through ahorizontal hole practiced in a lug or plate (177) welded to the side ofthe main tub (7), so that a spring to compression (178), fixed to thelower end of the bar, supports below of the hole of the lug to theweight of the tub. Thus, the combination of the free oscillation orangular rotation in a plane, over one of the shafts of the crosshead(191), of the lower “U” plate (192) together with the bar (141) and theoscillation or angular rotation of these over other shaft of thecrosshead, in the other perpendicular plane to the first one, allowsthat the bar (141) can oscillate angularly in any direction respect tothe supporting bar (193) of the crosshead, supporting to the tub in anylateral displacement limited of this. This system is similar, with adifferent use, to a universal transmission (“Cardan Joint”) of rotationbetween two shafts no aligned as are the bars (141) and (193).

The FIG. 20 is a vertical washing machine, as in FIG. 3, the eductor andits steam chamber (57) are fixed within the central post, and the inputof the feeding tube (8) is by the upper portion of the post.Furthermore, the supporting system (189) of the main tub of the FIG. 19,is used, so that the internal tub (14) can be centered within to thatrotating over its geometrical axis or shaft (194) within a centralbushing (185); thanks to this and to the stretch of flexible hose (102),the connectors of the pipes (8), (17) and (19) can be fixed to the maintub, in such a way that the washing machine can use the rotary washingsystem describe as follows.

In FIG. 20, the feeding tube (8), fixed to the main tub (7), penetratesdeeply by above within of the central post (1), fixed in its turn to thefeeding tube (8), wherein it is connected with the Venturi (39) of theeductor, so that the output tube (36) of this, stays as near as possibleto the bottom of the internal tub (14). Through a swivel coupling, withits supporting shoe of sliding (52) and rotary plate (50) as it wasdescribed, the output tube (36) of the eductor is articulated with arotary tube (48) which is short, of the same diameter and this is foldeda few grades respect to the vertical. The possibility that the rotarytube (48) be the shortest possible and that its folding be small, allowsto have losses by friction minimal on this, in comparison to the sametube of the FIG. 3. The suction of the eductor is fed directly, throughthe tube (38), by the steam chamber (57) and the electrical resistancewithin this is equally fed directly.

The central post (19 fixed has two helical plates (4) separated 180° onefrom the another one and, in the other hand, the bottom (45) of theinternal tub (14) is rounded from the center to the periphery, as amiddle toroid surface, in such a way that the bottom center raises aconical elevation (198) close to the end of the rotary tube (48); insuch a way that, dragging areas are formed between the surface (44) ofthe endings of the helical plates (4) and the curved surface (45) of thebottom of the internal tub (14). The output of the tube (48) staystangential to the curvature of the peak of the elevation (198) andplaced between this curvature and a small conical deflector (196)fastened around of the lower end of the central post (1). Thus, thewater jet and the bubbles discharged by the rotary tube (48) drag theclothes which are in such dragging areas, directing towards theperiphery of the tub wherein the current and the clothes, guided by thecurvature of the tub bottom, raise by the side of the tubs until theupper portion of these, to later return towards the bottom by the centerof the same tubs guided by the helical plates (4) again towards thedragging areas, to be impelled repeatedly by the jet which gets out ofthe eductor.

The lower part of the FIG. 20 shows, in the detail (195), an amplifiedof the system that drives the rotating short tube (48). The systemconsists firstly of a small motor (200), of slow speed, mountedvertically over a plate (199) within the central post (1). The shaft ofthis motor is coupled through a small pinion gear (201) with theperiphery in form of gear of the plate (50) of the rotary couplingbetween the tubes; in such a way that the plate also functions as gearimpels to make rotating the rotary tube.

The FIG. 21 is equal than FIG. 20, except that the connector of thefeeding tube is made by the lower part of the tubs. The feeding tube (8)is introduced below of the central part of the casing (23) of Peltonturbine and finish at the Venturi (39), so that this, the suctionchamber (37) and the output tube (36) of the special eductor, they stayhoused within a tube (100) whose upper end is welded centrally below ofthe internal tub (14), furthermore to be joined to the turbine Pelton(25). This tube (100), furthermore to be the passing duct of the eductorto the internal tub, also serves as the rotation shaft of this and ofthe turbine over the central bushing (185) of the main tub, thereforeits external diameter is adjusted to such bushing. In reason that theeductor is fixed, the chamber which generates steam (57) also is fixedand it feed of steam to the eductor directly by the tube (38).

To discharge the jet of the eductor within the internal tub, the rotarytube (48) is coupled, as it was described above, to the output tube (36)of the eductor, in such a way that the end of the rotary tube outstandsa little of the bottom of the internal tub by the passing tube and it iscurved the necessary to discharge radially the jet towards the peripheryof the tub; thus, the jet impels the clothes that is in the draggingzone, comprised between the bottom (45) of the tub and the helical plate(44), towards the periphery and upwards of the tub. The length and thecurved finish of the rotary tube (48) as small as possible to decreasethe pressure losses thereof, therefore it is convenient that the eductorenters within the shaft or passing tube (100), the most as high aspossible.

The rotary washing system is complete making to rotate in small pausesto the internal tub (14) together with the central post (1) and itshelical plates (4), impelled by the turbine Pelton; for this, the lowerend of the post is joined to the bottom of the tub through a thin legs(202) in order to allow the passing of the jet which launches the rotarytube (48). Within the central post (1) is a cylindrical box (80),fastened centrally to the structure (94) of the main tub (7), wherein ishoused a motor with speed reducer (200) which, by its centered shaft(201) joined to the rotary tube (48), makes rotating slowly to this sothat the jet which discharges radially goes running all the periphery ofthe tub. In such a way, during the washing cycle, can be alternated theperforming of the washing pump (18) with that from the centrifuging pump(149) so that this activates the rotation of the Pelton turbineintermittently, in such a way that the slow rotation of the helicalplates combine with the rotation of the rotary tube (48) to facilitatethe circulation of the clothes.

The bottom of the FIG. 21 shows with the number (195) the same zonemarked with the pointed circle in the above figure, to show that can beadded, as in FIGS. 5 and 7, a planetary reducer (2) between the centralpost (1) and the shaft (201) which move to the rotary tube (48), so thatthe post transmits its rotation to the rotary tube, without thenecessity of use a motor with the reducer (199) to make rotating thetube.

It is evident that the method of FIG. 21 to make rotating the centralpost together with the internal tub, joined centrally to the bottom ofthis through two or three legs, can be applied equally to the system ofFIG. 20, also activating the centrifuging circuit alternately and inshort pauses during the washing cycle.

The FIG. 22 represents an industrial washing machine for big quantitiesof clothes, which uses the principle of recirculation by pumping and thedischarge produced by a special eductor (as the described in FIG. 2) ofthe steam bubbles to low pressure which implode on the water and clothesbosom, as it was described in above figures.

In this FIG. 22 is observed that the washing tub (7) of this newindustrial washing machine consists in a tube, duct or canal ofrectangular path or another form, in addition to closed trajectory, ofenough length and with corners rounded to make easy the transit of thewater and the clothes through these. A special eductors series as thosein FIG. 2 comprised each by a Ventury (39), a discharge tube (36)without diffuser and a steam suction chamber (37) fed by the tube (38)from a steam generator or closed container (57) with heated water by aheater (56), they discharge water jets and steam bubbles to low pressurewithin the canal or duct. These eductors are placed in such manner thatalong the canal which impelled the water and the clothes within thecanal in a closed path around this, allowing the cleaning action of thecavitation of the bubbles over the clothes.

Each Venturi of the special eductor series is fed by the discharge tube(8) of a pumping system in closed circuit whose suction tube (19) of thepump (18) is connected to the canal bottom through a filter (203). Alongthe inner sides of the canal is placed a sloping-blades series (204) sothat this provoke the shoveled of the clothes in order to be changingthe relative position of this within the tub.

The FIG. 23, as continuation of FIG. 22, is the wringing system byrollers and rinsing of the washed clothes in the washing machine of FIG.22. This system consists firstly in a perforated band conveyor (207)placed above the straight portion of the canal which form the washingtub (7); such band is formed by two stretches o portions, so that thestructure (205) between the two guide rollers (206) from the initialstretch of the band can be descend in angularly form, rotating downwardsand the other portion stays horizontal by above of the tub. Finishingthe washing In the tub (7) from FIG. 21, the structure (205) of theinitial portion of the band, rotating angularly, is introduced slow andgradually in oblique form within the tub (7) until its bottom, while thewater continues circulates along with the clothing. The perforations ofthe carrier band (207) allow that the water continues circulating whilethe band retains the clothes and raises them to the final stretch andhorizontal of the band which carries until its end where it launchesthem over the other lower band (208) which take them to introducebetween the same band, supported over the guide roller (210), and otherwringing roller (209) pressured over the band, to wring the clothes bypressure. The wringed clothes between the band (208) or the roller (210)and the roller (209) is poured within the other tub (211), similar tothat of washing, in which is rinsed the clothes by the re-circulatingpumping of the water which comprises the pump (18), the suction (19) andthe discharge (8) with the nozzle (36).

The FIG. 24 is other version on the industrial washing machine whichuses the same washing and centrifuging systems above described to makeits work. The main tub (7) is formed by a closed canal in circle ofenough size, in such a way that the inner wall of the canal forms agreat diameter central cylinder (219) for the easy circulation of theclothes around thereof. The internal tub (14), as in the above figures,serves to centrifuging the clothes, has equal form than the main (7) andit is housed within this with certain separation between them. For thecentrifuging cycle, at the upper of the cylindrical body (219) is fixedcentrally a vertical motor (218) whose shaft, directed upwards,transmits its rotation to the internal tub (14) by a coupling (215)which fasts, by an arms (216), to the upper portion of the inner wall ofthe internal tub. On the other hand, the main tub (7) is supported,around its upper periphery, by a supports series (189) equal to thosefrom FIG. 19, which allow it to displace in any lateral direction, whilethe internal tub rotates, over its geometrical axis, impelled by thevertical motor (218), as it was described. To allow the freedisplacement of the internal tub (7) respect to the pipes from thepumping system, the pipes connected to the tub have intercalatedstretches of flexible hoses (102) as it was indicated in FIGS. 17 and18.

The washing by means of cavitation is produced, as it was mentioned, bymeans of a special eductors series whose suction is connected (38) to asteam generator (57), in order to be fed by a re-circulating pumpingsystem of the water into the tub, connecting the discharge (8) of pump(18) to the special eductor and the suction of this (19) to the filter(203) in the bottom of the main tub (7). The eductors point theirdischarge jets (36) within the tubs in adequate direction and from theupper of these. The feeding tubes of the eductor have a flexible portion(217) in order to can change the direction of the eductor jet during thewashing and in order to remove the eductor before removing the smallbasket described in the following paragraph.

Inside the internal tub is a basket (212) with the same profile or shapeof the internal tub, except that it does not have the outer wall and itis fastened by a hollow and central conical body (213), which indismountable form and of easy registration is coupled to an equalconical prolongation of the motor couple (215). The upper portion of theconical body (213) has an eyebolt (214) which serves to pull up with acrane the small basket and to remove the washed clothes.

FIG. 25 is a variant of the rotary washing system, similar to that fromFIG. 9, except that in this figure the balancing system in thecentrifuging is equal to that described in FIGS. 19 and 21, with thespecial supports (189) of the main tub (7), the bushing (185) for therotation of the internal tub (14) and the flexible hoses (102)intercalated in the connectors of the pipes. The steam feeding to theeductors without diffuser (221) is equal to that described in the FIG.9, wherein the generated steam in the fixed chamber (57) is conducted bythe tube (68) fixed to the closed box (108), in which the steam istransferred to the rotary vertical portion of the central tube (38)which carries the steam. Furthermore, in this case, the rotary tube (38)also serves as impeller shaft of the two planetary reducers (2) and(225) which move the central hollow post which is divided in twoportions. The upper portion of the post (224) rotates, impelled by theabove reducer (2) in a single sense such as the helical plate (4) joinedto this portion pulls to the clothes, as in above figures, downwards.The lower portion of the post (1) rotates oscillatory by means of thedouble planetary special reducer (225) from below, which operates insuch a way that the blades (12) joined to this portion of the postoscillate as a common washing machine. The steam transference to therotary tube (38) and the operation of the reducers impelled by this tubewill be described in detail in the following FIG. 26.

The feeding of the rotary washing system consists of a first greatdiameter fixed tube (101) which enters centrally below the centrifugingcasing (23) and it carries the flow which comes from the pump discharge,in similar form than in FIG. 9. This first tube is introduced into asecond tube (100) which gets down, joined in its upper portion to thecenter of the bottom of the internal tub (14), until support centrallythe Pelton-type special turbine (25). By above of the second tube (100)it is introduced into this third tube or rotary tube (48) until thisslightly assets by means of a shoe of sliding (99) over another shoe ofsliding in the upper edge of the second tube. The first and the thirdtube are introduced with fine adjustment as a sleeve bearing.

The upper end of the rotary tube (48) is extended gradually in conicalform (220) until finish off, centrally and by below, within a closedcylindrical chamber (97) of low height, great diameter and housed in thebottom of the internal tub (14), instead of the bell-shape chamber ofthe FIG. 9 or 7. To guide better the output of the flow in the upper endof the rotary tube (48) over this is placed a conical appendix (98) withthe vertex downwards. The water flow which is coming out from the rotarytube (48) circulates radially within the cylindrical chamber (97) and itis extended gradually within the successive concentric sections of thechamber, which increase their area according they are separated of thecenter. Thus, the speed of the flow is decreasing in its transit by theconical and by the cylindrical portion; in such a way that the pressurelosses by the change in the flow direction are minimal. Moreover, theflow is distributed within a section radial series of the chamber whosewalls (222) converge so that (see cutting BB′) each section guides theflow towards an output (107), circular and tangential, connected to theinput tube (40) of the Venturi from a respective eductor withoutdiffuser (221), placed in such a way that in the chamber perimeter (97)which its output short tube (36), a little curved, discharges in aconvenient and tangential direction water jets and steam bubbles whichproduce cavitation in the bosom of the clothes and impels, by reaction,the rotation of the cylindrical chamber over a rotary tube (48).Additionally are added in each section a curved and radial plates (223)for better guide of the flow towards the eductors.

The bottom enlarged portion (226) of the vertical portion of the steamconductor tube (38) is fixed centrally above the cylindrical chamber(97) so that the tube rotates with this and it serves as tube-shaftimpeller of the reducers, as it was mentioned. On the other hand, thesteam carrying towards the suction of the eductors (221) continues byother horizontal tubes (38) which radially are from the lower portion(226) of the vertical portion of the tube.

Since it is necessary for the operation of the planetary speed reducers(2) and (225) that the structure which supports the gears of these staysfixed, a bar (94) joined to the main tub (7) is welded to the steamtransference box (108) and which is integrated to such structure.

FIG. 26 shows in detail the system of the two planetary reducers (2) and(225), housed respectively in the upper (224) and lower portion (1) inwhich is divided the central post, and which produce the rotary movementof the helical plate (4) and the oscillating movement of the blades (12)as it was described in the FIG. 25. Both reducers are impelled by thesame vertical and central portion of the tube (38) which also carriesthe steam to the special eductors, as also was briefly mentioned in suchabove figure.

As well as in FIG. 9, the supporting structure (80) of the reducersgears is integrated to the box (108) which transfers the steam that iscarried by the fixed tube (68) to the upper end of the rotary tube (38)same which enters into the box through a passing hole with mechanicalseal (71) to avoid leaks. The box (108) is fastened to the main tub tofix the entire structure (80).

Below the box (108) is the planetary reducer (2) which comprises thecentral gear (79) mounted on the impeller tube (38) the intermediategear (96) and the box (244) of the peripheral external gear which, to bejoined to the upper portion (224) of the central post, makes rotating tothis and its helical plate (4) in a single sense. The reducer rotatessupported in the bushings (239) over a tubular rounded portion (227) ofthe structure (80).

The second reducer (225) which moves to the lower part (1) of thecentral post really is a double reducer with two systems, aligned oneover the other one, of planetary gears (233) and (243); each of thesesystems has a central gear (235) mounted on a hollow shaft (241), sothat these shafts are independent between them and they rotate over thealigned bushings (234). The upper end of the hollow shaft of the abovegear and the lower end of the hollow shaft of the below gear, protrudingfrom its bushings, have the radial bars (231). Inside the two hollowshafts or tubes (241) runs a ratchet tube (240) with other bars orvertical ratcheted bar (230) in each end in order they can be interlacedwith the radial bars (231). The length of the ratchet tube (240) is suchthat, moving upwards or downwards, it interlaces by itself with only oneof the two hollow shafts (241) of the central gears, keeping free therotation of the other gear. Within the ratchet tube (240) is theimpeller tube (38) which rotates in a single sense and drag in itsrotation, by a wedge (237), to the ratchet tube (240), which in its turnimpels the central gear to which is interlaced in this moment. The keyslot (236 in which is loosely housed the wedge is larger than this, sothat the ratchet tube (240) has enough freedom to displace upwards ordownwards.

It is observed, in FIG. 26 that in the upper system of planetary gears(233) the quantity of intermediate gears (232) is a non number and inthe bottom system (243) the quantity of this gears (242) is a pairnumber, therefore, to link to the ratchet tube (240), which rotates in asingle sense, to one or another system will make that one of themrotates in contrary sense to the other one. Thus in this way as theperipheral gears of the two systems are joined to the lower post (1)this will oscillate to certain frequency together with its blades (12),as it get up or get down alternately the ratchet tube (240). The centralpost supports its oscillation on bushings (239) which rotate over thetube (227) of the structure (80) at the upper portion and over the tube(38) at the lower part. The upper or lower vertical position of theratchet tube (240) is controlled by means of a spring (238) and theaction of a bobbin (229) over the magnetic nucleus (228) mounted on theratchet tube (240) or by the cam system.

FIG. 27 is a variant of the industrial washing machine of two tubs ofFIG. 24, in combination with the portion of the FIG. 25. In this newversion, the main tub (7) is cylindrical, large and has flat bottom, butit configures a circular canal closed together with the shape of theinternal tub (14), furthermore, the central connector to the washingsystem of the feeding tube (8), or of the discharge of the pump (18)from the closed pumping circuit, is vertically for the center ofunderside of the main tub, so that it is connected with a rotary tube(48), introducing this within that, with slight adjustment as sleevebearing. In this case, the upper end of the rotary tube (48) finishes ina conical shape and is joined to the bottom of the internal tub (14),moreover, as in FIG. 25, this tube is connected within a cylindricalchamber (97), which feeds to series of eductors (221) without diffuserwhose output tubes (36) direct its discharge over a dragging zone,formed this by a curved plates (44) joined to the central body of thebasket (212) and the bottom (45) of the same basket which serves toremove the washed clothes, as it was described. The central cylindricalbody (219), which constitutes the inner wall of the canal, is joined tothe upper portion of the cylindrical chamber (97), which likewise isjoined to the bottom of the internal tub (14), integrating a singlepiece. The supports (189) of the main tub, the steam chamber (57) andthe feeding tubes (38) of this to the eductor are the same described.

The rotation of the internal tub (14) in the centrifuging, which issupported in a shoe of sliding over a bushing (185) in the center bottomof the main tub (7), is impelled by a motor (218) whose vertical shaft(245) penetrates axially within the vertical portion of the feeding tube(8) through a hole practiced in the lower portion of a bend to 90° ofthe same vertical portion of the tube, sealing the passing of the shaftby a mechanical seal (71). The upper end of this shaft is joined to theinner of the lower end enlarged of the rotary tube (48) by radial arms(246) which not avoid the flow passing, so that the motor (218), whenoperates, impels to tube (48) together with the internal tub (14).During the washing the motor can rotate in opposite sense to the flowcirculation within the tub, so that the dragging zone displaces againstthis flow and improve the circulation of the clothes.

FIG. 28, is a variant of the washing system of a vertical washingmachine of two tubs (7) and (14) similar, in part, to the systems of theFIGS. 9 and 25. As in FIG. 9, the discharge (8) of the pump (18) isconnected, intercalating in this case a hose (102) between both, with acentral fixed tube (101) which enters into the centrifuging casing (23)and is fixed in this, to then crossing the bottom of the internal tub(14) through a passing hole slightly adjusted to the same tube, whichraises inside the tubs until close the upper portion thereof. At theupper end of this first tube (101) is introduced a second rotary tube(48), with light adjustment so that it can rotate within the first tube,which is supported by a shoe of sliding (99) over other shoe of slidingat the end of the first tube. It is observed that the system does notuse a central hollow post. In the centrifuged the centered rotation ofthe internal tub (14) within the main tub (7) is performed on thebushing (185), and to avoid the vibration is used, for instance, thesame system support (189) of the main tub of the FIG. 20 or 21.

The upper end of the rotary tube (48) finishes to the inner of a widenbell-shape closed chamber (97) of double wall, in a same shape and withthe same function that the similar chamber showed and described in FIG.9, except that, in this case, the periphery of the bottom of suchchamber (97) is connected by convergent surfaces, to the inputs of aseries of Venturi tubes (39) belonging to the special vertical eductorswithout diffuser, whose output tubes (36) discharge downwards water jetsand steam bubbles which cavitate in the bosom of the clothes, generatingcurrents which drag the clothes and which, guided by the curved bottom(45) of the internal tub, they follow closed paths on vertical planesfrom the center to the side of the tub and all around this. It isobserved in the figure that the eductor series (39) are slightlydeviated from the vertical a same angle, with the purpose that the smallhorizontal component of the jets reaction which get out by the outputtubes (36) impel, over the rotary tube (48), the rotation of the chamberand the eductor around the tub.

Additionally, to help the circulation of the clothes within the internaltub (14), in the bottom of this, are fixed the radial blades (12) whichrotate with the tub when the pump (149) is activated which feeds (17)the jets which impel the Pelton turbine (25) of the internal tub at thecentrifuging cycle, as it was described. This action is made in shortperiods during the washing, alternately with the performance of the pump(18) of the hydraulic circuit of the same washing; in such a way that inthis short periods, the clothes which are in the tub bottom are impelledby the rotation of the blades (12) towards the periphery, pushing andprovoking the movement of all the clothes within the currents producedby the eductors.

Finally, the steam feeding to the eductor is made in similar form tothat described in FIG. 9. On the cupola center of the bell-shape chamber(97) is fixed a closed box (108) for the steam distribution by means ofa tube series (38), connected to the inner of the same box, and whichcarries the steam to each of the suctions of the different eductors inwhich finishes the bell-shape chamber (97). In its turn, the closeddistribution box (108) is fed by a tube (68) which enters into the box,by above, through a center bushing and adjusted to the tube, so that thebox can rotate over the tube (68) which carries the steam from the steamfixed chamber (57). The input of the tube (68) is sealed by a mechanicalseal (71).

1. A washing, rinsing, wringing machine for clothes within a main tubwhich contains another inner tub with holes for the passing of the waterflow towards the main tub; wherein, the tubs are connected in serieswith a hydraulic closed pumping circuit which consists of a pump whichtakes continually the water from the inner of the tubs and thedischarge, through a feeding tube, again within them, to produce theenergy of the re-circulating water flow which moves to the systems; thedischarge of the pump is connected, by control valves, either to thewashing system or to the wringing by centrifuging to activate to any ofthe two systems or it is used, optionally, a centrifuge pump for thehydraulic washing circuit and other for the hydraulic centrifugingcircuit, each of which works with different rotary sense and they areimpelled by a same motor which has rotation change to activate one oranother pump; firstly the closed pumping circuit feeds and activates thewashing system which consists of a special eductor without diffuserwhose suction is connected to a steam generator to low pressure; thisgenerator is a closed steam chamber in which a heater heats the water,direct or indirectly, so that the eductor discharges, in certainadequate direction within the washing tub, a water jet with steambubbles which cavitate in the bosom of the clothes for wash; within thewashing tubs is a dragging zone of the clothes, or deflector space ofthe flow, limited by two surfaces separated to certain distance, on infront of the another one, warped against and converging in certaindegree, in such a way that the water and steam jet which gets out by thedischarge of the eductor directed towards such zone, in direction of theconvergence, produces a positive thrust over the clothes in this zone,so that the same go circulating for such space; furthermore, the machinehas a rotary washing, moving and circulation system of the clotheswithin the tubs which is activated by the water flow of the closedpumping circuit and it is comprised of a broad tube or hollow post ofgreat diameter housed centrally within the tubs and called centralhollow post; this post has a helical wide plates welded in its aroundand along; the rotation of the wide hollow post, which can be continueor slowly controlled by means of a special mechanism, is produced,through a direct coupling or planetary speed reducer, by a motor shaftcentered with the post and impelled by an axial flow turbine or by arotary tube, also as center motor shaft, which conduces the water flowof the system to be connected, by means of a rotary or swivel couplingbetween both tubes, to the end of the feeding fixed tube at turn thatcan rotate on this impel by reaction jet; the feeding fixed tube isintroduced centrally by the upper or lower of the tubs; for produce theimpulse of the rotary tube is used a system of make in this two foldingto 90° in its free end which place to the output of the tube inperpendicular position and to certain distance of the geometrical axisor of rotation of the own tube, in such a way that the water jet whichgets out from the tube origins, by reaction, the pair of forces whichproduce the rotation, at the same time that the jet is projected in thedirection of the dragging zone; this dragging zone is formed with thelower end of the helical plate as upper surface and, as low surface, thesame surface of the tub bottom, or the surface of a horizontal platewelded to a rounded cover, within which is the folded portion of therotary tube whose final end protrudes of the cover by a radial planewhich interrupts the form of this, being this cover separated orintegrated to the central post, in front of the dragging zone adeflector plate stays placed, which deviates the water flow a littleupwards and to the periphery of the tub; as option to move the clothes,are used two planetary central reducers, aligned and with differentrotary sense, coupled to the hollow central post which has radial bladesat its lower end, in such a way that a tube or centered shaft, whichrotates in a single sense, impels alternately by certain ratchet systemto the central gear of each reducer to produce in the post and theblades a oscillating movement; the eductor is connected to a series withthe feeding tube or with the rotary, before or after of the rotarycoupling between them, and it forms part of the water conduction; thesteam chamber and the eductor can be fixed or rotate together with therotary system; if the steam chamber is fixed and the eductor rotateswith the rotary system, the steam conduction between the steam chamberand the suction of the eductor is made by means of a first stretch ofthe fixed tube which comes from the steam chamber and connected to asecond stretch which rotates feeding to the suction of the eductor,therefore it is used a rotary or mechanic seal intercalated between bothtubes; if the steam chamber rotates together with the rotary washingsystem, the heat of the water within it is made indirectly by a electrictransformer whose primary is fixed and the secondary rotates with thesystem, fed to the same time to a electric resistant within the chamber;or also it is effectuated using a heater close to the walls of thechamber or the system of a pair of metallic isolated rings which feedelectrically by brushes, are mounted on a shaft which rotates togetherwith the steam chamber and they are connected to the resistance bysealed wires; additionally the tubs have in their inner side widehelical plates to guide the circulation of the clothes, and is disposeda system in the entrance of the pump which disintegrates and grind theloose threads coming out of the clothes; the clothes wringing system bycentrifuging in the inner tub consists on produce the rotation of thisby means of an horizontal turbine special Pelton-Type, joined to thecenter below of the tub bottom, which impelled by the water jets whichprovide a peripheral nozzles series connected to the discharge of thepump from the corresponding hydraulic circuit, so that the turbinehoused within a cylindrical box or casing, called centrifuging chamberand is as prolongation of the main tub bottom; this Pelton turbineconsists of a vertical box in which is introduced to the middle and theyare fixed to its side, a distributed series of ladle-shape radialbuckets; these buckets direct their output inner edges, slopping alittle downward, in almost radial form towards the center of the box,wherein this is connected with a vertical discharge tube from which isevacuated the jets water which impel to the turbine; so that therotation of the inner tub be balanced, this makes rotating while itfloats in the contended water, to certain prefixed level, within themain tub, in such a way that the inner tub rotates freely respect to anyvirtual axis which passes by the center of gravity of the tub and theclothes; furthermore, below the tub is placed a centered counterweightto stabilize the flotation of the inner tube; the machine has a systemto condition the flotation of the inner tub within the main tub, whichconsists, after previously draining the water of the main tub, inevacuate by gravity the water of the inner tub through the check valves,then to fill again of water the space between the tubs to the prefixedflotation level; another system to provoke that the inner tub rotatesover any virtual axis which passes by its center of gravity are used thespecial supports which support to the tub allowing it to displace,freely, in any lateral direction or around of the virtual axis, to theturn that the same rotates over its geometrical axis, in such a way thatthe result of both movements is the rotation of the tub over the virtualaxis, without supporting over a rigid or fixed axis or shaft; the pipeshave intercalated stretch of flexible hoses to not limiting that the setof tubs and the connectors to these from the same pipes can movelaterally; to close the virtual axis to the geometrical axis of theinner tub, this has a peripheral closed chamber which store certainquantity of a heavy flow; in this case the balancing chamber is annularand forms all the side of the inner tub, in such form constructed whichavoid the redistribution of the balancing flow within this to close,when increase the balancing, the virtual axis of rotation to thegeometrical axis of the same tub; the inner tub is just of the necessaryheight to contain to the wet clothes, situated in its bottom before thecentrifuging, and its side is housed within a broadening which the maintub has for such purpose, remaining certain space to contain the waterin which the inner tub floats and rotates; the separation between theupper edge of the inner tub and the broadening step from the main one,is covered by means of a annular gate with “L”-shape section, whosevertical portion is slightly adjusted to the diameter of the main tuband the horizontal portion is supported in such upper edge by materialplates resistant to the friction; if the inner tub floats, this isdamped in its oscillation to rotate by anti-friction plates or bearingsplaced between the bottoms of the two tubs and between the lateralportion from both; if is used a rotary tube and the inner tub does nothave output holes by flotation reasons, it is placed within the innertub a third tub with multiple perforations, separated a little fromthat, in such a way that the water flow is drained by a verticaldraining tube centered in the inner tub bottom and which is prolongeduntil near the bottom of the centrifuging chamber, wherein is the mouthof the suction tube of the pump, the draining tube has a check valvewhich avoid the return of the water to the inner of the tub.
